    Preface

    As Singapore enhances the importance of Workplace Safety and Health (WSH), the management of

    lifting activities has been identified as a high risk operation which requires proper planning and

    execution. This Code of Practice (CP) has been developed to provide guidance on how to conduct

    such lifting operations safely. It highlights factors that need to be considered during the planning and

    execution of the operation and introduces the Lifting Plan as a systematic approach towards planning a

    lift. The CP also outlines the roles and responsibilities of those involved in a lifting operation.

    This CP is aimed at practitioners who are involved in lifting operations, particularly those who plan

    these operations and the supervisors of those personnel in the lifting team.

    This CP was produced after extensive analysis of current practice in Singapore. It is intended to

    provide examples of good practices, assembled by specialists in the field. It is not meant to be

    prescriptive or imply that there is only one way of doing things, nor is it intended to replace or takeprecedence over recommendations, policies and procedures judged as safe as or safer than those

    given herein.

    Individuals and companies should use the CP as the preferred standard and that they should continue

    to find ways to exceed and improve upon the practices detailed within.

    There are many modes and methods of conducting a lifting operation. This CP is not intended to cover

    each one in detail, but does provide guidance on the minimum expectations required during the

    planning and implementation of a lifting operation. The same principles can be applied whether a large

    500 tonne or a smaller lifting device is being utilised for the lifting task. While this CP recognises that

    companies may have their in-house operational procedures, this CP has been developed to provide a

    minimum operational expectation and requirement while providing guidance for the conduct of safe

    lifting operations.

    Note: This CP will replace the Technical Advisory for Safe Operation of Lifting Equipment published

    by WSH Council in May 2009.

    This CP was developed by the following industry-led Workgroup formed under the National CraneSafety Task Force of the WSH Council. Members of the Workgroup dedicated their time in their

    individual capacity to make this CP possible. Representatives from the Ministry of Manpower (MOM)

    as well as from the WSH Council were also actively involved and provided the necessary supports in

    the development.

    1.3 Purpose

    Lifting operation is an integral part of any construction, ship-building, ship-repairing or manufacturing

    process. Every lift carries a set of risks that needs to be managed in order to prevent an accident from

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    7/38

    Page 7of 38

    occurring. Unsafe lifting operations can result in catastrophic outcomes involving multiple fatalities and

    serious injuries as well as extensive damage to properties and facilities.

    This CP has been prepared based on the collective experience from past accidents and good

    practices in safe lifting operation. It provides practical guidance for the practitioner in the planning and

    execution of a lifting operation. This CP is not intended to provide technical details on any specific

    lifting equipment; hence it is recommended to consult the manufacturer or supplier when more

    technical details are required.

    1.4 Regulatory Requirements

    The WSH Act imposes a duty on occupiers, employers to take reasonably practicable measures to

    ensure the safety and health of persons at work. In addition, the Act imposes duties on suppliers,

    erectors of equipment such as cranes to ensure that the equipment is safe when properly used. The

    imposition of such duties is in addition to the more prescriptive requirements that can be found in the

    subsidiary legislation such as the WSH (Construction) Regulations, as well as the WSH (Operation ofCranes) Regulations that will take effect on 1 September 2011.

    This CP is developed to help stakeholders fulfil their statutory obligations under the Act in order to

    achieve a higher objective of ensuring a safe lifting operation. It complements the existing Singapore

    Standards and Code of Practices that have been developed on safe use of lifting equipment.

    SECTION 2: FACTORS AFFECTING SAFE LIFTING OPERATIONS

    2.1 General

    There are many factors that can affect a lifting operation and it is important that personnel involved in

    lifting operations are aware of such factors. Broadly, they can be classified into the following:

    Machine this refers to selection of appropriate lifting equipment for the job as well as the

    integrity of the equipment to perform the job;

    Material this refers to the load that is intended to be lifted;

    Medium this refers to the environment in which the lifting operation is to be carried out

    and includes the setting up and stability of the equipment;

    Man this refers to the competency, roles and responsibilities of personnel involved in the

    lifting operation; and

    Method this refers to the planning and procedures to be adopted for the lifting operation.

    Routine versus non-routine lifts

    A lift can be categorised as routine if it is repetitive in nature and involves loads that are similar in

    terms of shape, size and weight i.e., multiple lifts of similar items. The underlying principle is that

    the risks involved in a routine lifts are already known and mitigated.

    Non-routine lift refers to lifting operations that are complex, carried out for the first time or lifting

    close to the lifting capacity of the crane. For example, a tandem tilt-up operation (i.e., lifting

    using two or more cranes to tilt a long structure from horizontal position to vertical) is a complex

    non-routine lift and it would require a detailed risk assessment and engineering method before

    the lift is carried out. Specific control measures to mitigate the risks involved in such a complex

    operation will need to be put in place. For example, in order to address the risk of a long structure

    buckling during a tilt-up operation, the numbers and location of lifting lugs will need to be

    considered in the design and built into the structure to be lifted. In short, a non-routine lift will

    require extensive planning.

    Notwithstanding the above, it is a misperception to assume that so long as the weight of the load

    is below a certain tonnage, it can be classified as a routine lift and therefore require less planning

    or supervision.

    Based on past experiences, most crane accidents happened during routine lift rather than non-

    routine lift. Hence, in essence, any lifting operations whether routine or non-routine warrant the

    same level of safety considerations.

    The following paragraph outline each of the listed factors in more detail and identifies areas that must

    be considered before lifting is carried out. It is important to note that the areas highlighted below are by

    no means exhaustive. Where more details are needed, users are advised to refer to the operating or

    maintenance manuals, or the supplier/ manufacturer of the equipment.

    2.2 Machine

    2.2.1 Sizing of the lifting equipment:One of the most critical factors in planning a lifting operation

    is to ensure that lifting equipment selected for the job has sufficient lifting capacity and reach to

    handle the intended load. In the case of a tower, mobile, crawler or a lorry crane, the lifting capacity is

    dependent on the load radius of the crane boom and hence it is important in the selection of the crane,

    that the distance from the loads to the crane is known. This meant that the loading and uploading

    points within the worksite must be carefully considered relative to the location of the crane. For lifting

    operations involving multiple loads of varying shapes and sizes, the capacity of the crane should be

    selected based on the weight of the heaviest load so as to avoid any overloading.

    2.2.2. Maintenance of the lifting equipment:Another important aspect is the maintenance of the

    lifting equipment to ensure its structural integrity. Based on past incidents, attention needs to be

    focused on critical load bearing parts such as the following:

    Wire ropes: There are many types of wire ropes for different usages and hence the

    correct type must be selected for the equipment. The wire ropes must be properlymaintained (lubricated) to prevent the ropes from snapping during operation;

    Braking mechanism: The ability of the lifting equipment to lift or suspend a load is

    dependent on the brakes connected to the hoisting mechanism. Any failure of the brakes

    would result in an unintended free-fall of the suspended load; and

    Safety devices: Most lifting equipments are equipped with a variety of safety devices such

    as limit switches or sensors. The safety devices will stop or prevent the lifting equipment

    from entering into an unsafe mode of operation, for example, an anti two-blocking device

    on a crawler crane serves to prevent the hook block assembly from coming into contact

    with the boom sheave assembly. It is therefore critical to ensure that such safety devices

    are functioning properly. They should never be by-passed during a normal operation.

    Further explanation is provided in Section 4 of this CP.

    2.3 Material

    There are a few key factors to consider in lifting a load. They are:

    2.3.1 Weight This is perhaps the most important parameter that must be determined to prevent

    overloading of the lifting equipment. When the load is part of an assembled item, the weight of each

    component can be determined from the engineering drawings. Other times, one must rely on estimate

    based on density of the load that is being carried, such as concrete or rebars. Special attention is

    essential when the load comprises different materials such as in a rubbish bucket containing waste

    and debris. It is safer to be extra caution and estimate a heavier weight than to assume a lighter one.

    2.3.2 Centre of Gravity (CG) During lifting operation it is critical to maintain the CG of the load

    directly beneath the load-line, i.e., hook. Otherwise, when the load is lifted, it will swing towards the CG

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    10/38

    Page 10of 38

    and this can be dangerous as any person closeby can be hit by the swinging load. Depending on the

    shape and size of the item, the centre of gravity may or may not be obvious. When in doubt, it is

    advisable to consult an engineer.

    2.3.3 Method of rigging There are different methods of rigging that are well established in the

    industry. They all serve to achieve the objective of ensuring that the load is stable throughout the lifting

    operation. For loose items, such as bricks and bags of concrete, it is critical that they are secured

    using an appropriate receptacle such as safety nets or metal cage to avoid any accidental

    dislodgement in mid-air.

    2.4 Medium

    Once the lifting equipment is selected and the load is known, the planning must then focus on the

    environment in which the lifting equipment is to operate in and how the lifting equipment is setup.

    Besides environmental weather conditions, every work site will have specific localised hazards which

    must be considered and the risk eliminated or mitigated in order to ensure safe lifting operations. Thefollowing are some of the factors which must be considered. They are presented using an acronym

    GOLDEN for ease of reference.

    2.4.1 Ground this refers to the setup of the lifting equipment at a specific location. The stability of

    the lifting equipment is highly dependent on the ground condition. Special care must be taken to

    ensure that the ground is level and has sufficient bearing capacity. Cranes that are equipped with

    outriggers should be evenly extended. In addition, when using mobile or crawler cranes, it is

    recommended that steel plates with adequate strength and size be used to provide a firm ground

    support for the crane outriggers in order to prevent any crane toppling incidents.

    2.4.2 Obstacles this refers to any fixed or temporary installations (such as nearby building, MRT

    tracks, overhead power lines, bridges or underground utilities/ pipelines) in the zone of operation

    where there is a risk of the lifting equipment or load coming into contact with the installations resulting

    in accidental dislodgement of the load. Obstacles could also take the form of blind spots or entrapment

    points during manoeuvring of the load or lifting equipment, especially in congested areas.

    2.4.3 Lighting condition the adequacy of the lighting condition particularly during night operation

    cannot be under-emphasised. Depending on the lift, the operator, rigger or signalman will need to see

    the suspended load in order to guide it to its safe destination.

    2.4.4 Demarcation the zone of operation should be demarcated to inform or prevent persons who

    are not involved in the lifting operation from entering into zone unintentionally. For operations involving

    tower cranes, dockside cranes at the wharves or even overhead travelling cranes where the crane are

    in continuous operation and the zone of operation spans a wide area, it is recommended that in

    addition to designating the affected zone of operation, other measures should be taken to prevent

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    11/38

    Page 11of 38

    persons from coming under the suspended load. Such measures could include deployment of more

    signalmen to guide the load or installing audible alarm to warn workers about the on-going lifting

    operation.

    2.4.5 Environment this refers to the weather conditions such as heavy rain, haze or glaze which

    impact the visibility of the lifting crew. Other weather conditions which could directly impact the stability

    and safety of the lifting operations include strong winds, thunderstorms or lightning situation. It is

    important to note that wind speed is stronger at higher grounds. During the planning of any lifting

    operation, the anticipated wind speeds at the site must be considered and made reference to the crane

    manufacturer operation manual on the wind speed limit. It is always advisable to stop all lifting

    operations when the weather condition deteriorates.

    2.5 Man

    Investigation into past accidents revealed that human error is the most common causes of accidents

    involving lifting operations. Therefore, it is paramount that every single member of the lifting crew(operator, rigger, signalman and lifting supervisor) is adequately trained and competent to carry out his

    duties properly. They must also be fully conversant with the actual lifting procedures applicable for that

    lifting operation and not just the generic procedures. The following are some of the factors that should

    be considered:

    2.5.1 Fit for duty besides the pre-requisite of competency (such as ability to read load capacity

    charts), the fitness of the personnel, such as any existing medical conditions or length of working hours

    that could adversely affect his ability to discharge his duties must also be considered.

    2.5.2 Roles and Responsibility these must be clearly spelt out to the individuals involved in the

    lifting operations. There must be clear leadership within the lifting crew such that instructions are

    appropriately relayed. In addition, all personnel must be empowered to stop work if they see or believe

    that the operation is or has become unsafe.

    2.5.3 Communications this refers not only to the provision of communication devices such as

    radio walkie-talkie or application of standard hand signals, but also ensuring that there is common

    understanding between members of the lifting crew. Employers must consider the composition of the

    lifting crew taking into consideration that the local workforce comprises workers from various countries

    with different languages and cultures.

    Further explanation is provided in Section 5 of this CP.

    2.6 Method

    Most general type of lifting operations rely on established procedures after taking into consideration

    factors such as Machine, Medium and Man as previously discussed. These types of lift are typically

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    12/38

    Page 12of 38

    categorised as routine lifting operations. Whether the lift is routine or not, the following outline some

    important factors along the life-cycle of a l ifting operation that needs to be considered:

    2.6.1 Knowing the weight of the load and the load radiusthe general rule of thumb should be

    that if the weight of the load is unknown, it is always safer not to lift as it could lead to overloading and

    toppling of the lifting equipment.

    2.6.2 Securing the load using appropriate lifting gears such as slings, nets or receptacle if

    the load is improperly rigged up or part of the load is loose, there is a risk that during lifting, the load

    might dislodge and drop while being transferred from one location to another.

    2.6.3 Conducting a test lift to ensure stability and no overloading a test lift is simply lifting the

    load just slightly off the ground and stopping to observe for any abnormalities. This is a critical

    discipline that all operators must learn to abide by.

    2.6.4 Maintaining the centre of gravity (CG) of the load directly beneath the load-line i.e. the

    hook if the CG is not directly beneath the load-line, once the load is l ifted off the ground, it will swing

    and this is dangerous. In addition, it is important to note that pulling or dragging the load is strictly

    prohibited as it can destabilise the crane.

    2.6.5 Stability of the suspended load during movement/ slewing of the crane while moving/

    slewing the crane, the load should be prevented from jerking or swinging at all times.

    2.6.6 Lowering / releasing of the suspended load towards the end of the lifting operation, the

    load must be placed on a stable ground. If it had been placed at heights, care must be taken to ensure

    that there is no risk of the load dropping off the edge to a lower level. Often times, the load is lifted to a

    point beyond the line of sight of the operator. Under such circumstances, the responsibility to ensure

    the stability of the suspended load lies with the signalman and/ or lifting supervisor.

    It is critical to note that no lifting equipment or lif ting gear shall be loaded beyond its safe working load

    except by an authorised examiner or an inspector for the purpose of testing such items.

    SECTION 3: LIFTING PLAN

    3.1 General

    Under the law, it is mandatory to conduct a risk assessment1on the safety and health risks posed to

    any person who may be affected by the lifting operation in the workplace. The contractor involved is

    also duty-bound to take all reasonably practicable steps to eliminate any foreseeable risk to any

    person. In addition, there are legislative requirements for lifting operations involving tower, mobile or

    crawler crane in any workplaces to implement a Permit-To-Work system in order to effectively control

    lifting operations.

    In order to assist the contractor discharge their duties and put in place a system to ensure safe lifting

    operation, a Lifting Plan (LP) that harmonised the requirements for risk assessment and Permit-To-

    Work is recommended in this section.

    3.2 Risk Assessments and Permit-To-Work

    3.2.1 Risk Assessment (RA) By definition, RA is the process of evaluating the probability andconsequences of injury or illness arising from exposure to an identified hazard, and determining the

    appropriate measures of risk control. As such, there are three basic steps to RA:

    Step 1 - Hazard Identification

    This involves identifying the hazards associated with each work activity and the type of

    potential accidents/ incidents that can result from the hazards. Some of the hazards associated

    with lifting operations such as poorly maintained wire ropes have already been discussed in

    Section 2: Factors Affecting Safe Lifting Operations.

    Step 2 - Risk Evaluation

    This refers to the process of estimating the risk levels of the identified hazards in terms of the

    severity of any injuries/ damage if an accident were to occur and the likelihood of the

    occurrence. For example, the risk level of workers working underneath a suspended pre-cast

    component should be assessed as high risks as the consequences of the load dropping could

    result in killing the workers underneath.

    Step 3 - Risk Control

    This is a critical last step as it identifies appropriate risk controls measures so as to reduce the

    risk level to an acceptable level. Following from the last example of a suspended pre-castcomponent, an appropriate risk control measure would be to prohibit workers from working

    directly underneath a suspended load. The lifting zone should also be demarcated to prevent

    any unauthorised entry.

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    14/38

    Page 14of 38

    3.2.1 Permit-To-Work - A Permit-To-Work System (PTW) is a formalised system of controlling

    certain types of hazardous work (lifting operations included). A proper PTW involved the contractor

    applying for permission to carry out a certain work activity. In the application, he would state the scope

    and the conditions in which the work is to be carried out. An independent inspection is then conducted

    on-site to verify that appropriate control measures have been taken to mitigate any foreseeable risks.

    After confirming that the measures have indeed been taken, the application would then be approved by

    an authorised person (typically the project manager) who shall have oversight on the entire work

    process so as to avoid any situation of conflicting or incompatible work being carried out at the same

    time. The work can commence only after the permit is approved.

    3.3 Lifting Plan

    Section 2 discussed the factors affecting the safe lifting operation and it is intended to provide

    guidance to the personnel planning for a lifting operation. A Lifting Plan should be developed based on

    the consideration of the factors listed Machine, Material, Medium, Man and Method. Depending on

    the complexity of the lifting operation, details to be considered in the Lifting Plan will vary.

    3.3.1 The primary objective of the Lifting Plan is to facilitate common understanding amongst the

    lifting crew for a safe outcome. The underlying principle is that all foreseeable risks are assessed and

    eliminated / mitigated.

    3.3.2 In order to provide practical guidance, a template of a Lifting Plan is developed (see Appendix

    2). The suggested template addressed key factors affecting safe lifting operations:

    details of the load;

    details of the lifting equipment / lifting gears used;

    means of communications;

    personnel involved in the lifting operation;

    physical and environmental considerations;

    sequence/ special precautions; and

    sketch of the zone of operation.

    3.3.3 Notwithstanding the above template, it is important to note that the factors recommended in

    the Lifting Plan are by no means exhaustive and personnel involved in planning lifting operation must

    consider factors that are unique to the situation, particularly for complex lifting operations.

    3.4 Harmonisation of the Lifting Plan vis--vis Risk Assessment and Permit-To-Work

    3.4.1 A RA for lifting operation would typically specify control measures such as appointment of

    competent personnel, usage of appropriately maintained lifting gears or demarcation of the lifting zone.

    These are needful and useful assessment, and should take into account the physical environment.

    3.4.2 The Lifting Plan and the PTW system are actually part of the Risk Control stage of the RA

    process. A proper Lifting Plan/ PTW serves as a means of verifying that the necessary control

    measures have indeed been taken. They are complementary and should not be seen as mere paper

    exercises.

    3.4.3 If the sample Lifting Plan/ PTW template recommended in Appendix 1 is used properly, it

    would meet the legislative requirements for Lifting Plan and PTW.

    3.5 Changes to Lifting Plans

    As the Lifting Plan is developed based on a pre-determined set of parameters and consideration, any

    significant changes should result in a temporary stoppage of the lifting operation and a review of the

    Lifting Plan conducted. The following scenario should result in a review of the Lifting Plan.

    Changes to the type and capacity of lifting equipment used.

    Changes to the sequence of operations. Changes requiring reconfiguration of the crane (boom/ jib length, outrigger beam length

    reduction, parts of hoist line, etc).

    Changes in the rigging details which could result in a reduction in rigging strength or

    significant increase in rigging weight.

    Changes in surrounding environment such as sudden presence of a temporary structure

    obstructing the operation.

    Changes in the weather and environmental conditions which have an adverse impact to

    the lifting operation.

    Changes to safety-critical personnel.

    SECTION 4: EQUIPMENT

    4.1 General

    This section provides guidance for the selection, maintenance and other aspect of the lifting

    equipment.

    4.2 Selection of Equipment

    4.2.1 An equipment assessment must be completed as part of the RA. The objective of the

    equipment assessment is to identify the hazards and assess the risks associated with the equipment

    for the foreseeable range of lifting operations, for example, the applications, loads and configurations

    for which the equipment might reasonably be used. Based on this assessment, the appropriate lifting

    equipment for the lifting operation may then be selected.

    4.2.2 The equipment assessment shall consider, but not necessarily be limited to the following.

    Is the equipment designed for this intended type of lifting operation?

    What is the age of the lifting equipment? Was there any authorised modifications made to the equipment?

    What are the dismantling and assembly process?

    How are components of the lifting equipment transported to site for assembly?

    What type of pre-erection examination or Non-Destructive Testing (NDT) is required?

    How is the lifting equipment controlled e.g. via pendant or within the operator cabin?

    What are the access and egress for the operator to reach the cabin?

    What are the dismantling and storage requirements?

    What transportation methods to use for continued integrity?

    4.2.3 Owners of lifting equipment must not install additional components that may affect the

    structural integrity of the lifting equipment e.g., adding counterweights beyond what is specified in the

    manual. In general,structural modification of lifting equipment should not be undertaken except by a

    competent party. If the lifting equipment has to be modified, a detailed engineering design must be

    undertaken in consultation with the manufacturer or a professional body. The design must take into

    account prevailing design codes, standards and practices as well as compliance with all applicable

    regulations.

    4.3 Equipment Positioning and Installation

    For the purposes of this CP, the term positioning refers to mobile equipment being set up in a

    particular location to carry out lifting operations. The term installation refers to the assembling of lifting

    equipment at the selected location.

    4.3.1 A process shall be established to ensure that the contractor reviews the positioning/installation

    of lifting equipment to eliminate or mitigate the risks. All hazards identified in relation to the position/

    4.5 Lifting Equipment with Variable Safe Working Load (SWL)

    4.5.1 Some lifting equipments are designed to operate with variable SWL. Examples of such lifting

    equipment include mobile crane equipped with a telescopic jib that can be raised or lowered. Tower

    cranes are also designed to have variable SWL. In principle, the closer the load is to the body of the

    crane, the higher will be the SWL of the equipment.

    4.5.2 For such lifting equipments, besides the mandatory load capacity chart, they must be equipped

    with a load radius indicator to indicate to the operator the SWL of the crane at that configuration (load

    radius). It should also provide a visual and audible warning to the operator should the load lifted be

    close to SWL. Consequently, due to the variable SWL, the crane operator must exercise extreme care

    whenever he lowers the jib or telescope the boom outwards with a load as this will lead to a reduction

    of the SWL and potentially overloading the crane.

    4.5.3 For lorry cranes, if the Load Radius Indicator is not feasible, it must be equipped with fully

    hydraulic protection valves and pressure relief system to prevent crane overloading.

    4.5.4 Some modern cranes are designed such that a different load capacity chart will apply

    depending on whether the outriggers are fully extended or partially extended. Under such

    circumstances the operator must be fully aware of the configurations and make the necessary

    adjustment to the parameter settings of the indicator. Information about how changes to the

    configuration affect the SWL must be provided in the operators cabin. They should not simply be kept

    in the office as this denies the operator critical information he may need to perform a certain lifting

    operation.

    4.6 Pre-use Checks

    4.6.1 Prior to use, the operators of lifting equipment and accessories shall perform a pre-use check

    in order to identify any faults in the equipment. This should be a daily check at the start of each shift.

    This daily inspection is not intended to replace the period preventive maintenance checks by the

    mechanics. Sample checklists for various cranes are provided in Appendix 2, 3, 4 and 5 for reference.

    Useful tools

    As it is insufficient to solely reply on the crane electronic system, it is recommended that all mobile

    and crawler cranes be equipped with the following tools to allow the crew of lifting team to use them

    during crane setup/ or pre-use checks:

    Measuring tape - As the crane's rated capacity depends on the radius of the load which is the

    distance the load rest from the crane. The simplest and most accurate means of determining a

    radius is a tape measure. Without a tape measure, a crane operator is force to guess at the

    lifting radius or use a less accurate boom angle determination to verify the crane's capacity.

    Calculator The mathematics necessary to determine if a crane will be lifting 78% or 91% of its

    rating chart for a specific lift can be challenging problem for many crane operators. A calculator

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    19/38

    Page 19of 38

    circumvents this problem allowing the operator to focus on the details of the lifting rather than

    arithmetical errors.

    Spirit level gauge One cannot just rely on the one that provided with the crane. At time it may

    not be accurate that the crane set up is level. The additional portable spirit level gauge that you

    can purchase from DIY shop will give additional verification and insure level of balance from front

    and rear of crane.

    Calliper This provides the crane operator as part of the daily crane checks to ensure that the

    crane wire rope provided is according to crane manufacturer specification. The checks includes

    whether the wire rope has a reduction in diameter that can be cause by abrasion, corrosion or a

    local failure of the rope core due to its prolong use during its life span.

    SECTION 5: PERSONNEL ROLES AND RESPONSIBILITIES

    5.1 General

    This section outlines the responsibilities for all personnel and entities that are involved in the lifting

    operation.

    5.2 Contractor

    5.2.1 The overall responsibility to ensure the lifting operation is carried out safely and in

    accordance with legislative requirements rests with the contractor undertaking the lifting operation. The

    contractor could be the employer or the principal of the operator under whose direction he operates the

    crane (termed as a responsible person in the WSH (Operation of Cranes) Regulations, with effective

    date 1 September 2011). The contractor shall:

    ensure a safe system of work is implemented and all foreseeable risks are identified and

    control measures implemented to eliminate or mitigate the risks through the

    implementation of a Lifting Plan and PTW system;

    ensure that the worksite is physically safe for the lifting operation e.g., there is no physicalobstruction in the path of the load;

    ensure that the lifting equipment to be used is properly maintained and duly certified in

    accordance with legislative requirements;

    ensure that the lifting operation has the necessary resources to carry out the lift safely,

    e.g., receptacle for lifting loose items;

    ensure that personnel deployed as part of the lifting team are suitably trained, competent

    and certified, and that they had been briefed on the lifting operation;

    ensure that only competent sub-contractors are used; and

    ensure that all accidents, near misses, equipment failure or damage are reported and

    recorded.

    5.2.2 The contractor may appoint a competent person such as a WSH Officer to assist in the

    identification of any hazards related to the lifting operation and recommend suitable actions to

    eliminate/ mitigate the risk.

    5.3 Lifting Team

    The Lifting Team refers to a group of personnel that is appointed to be directly involved in the lifting

    operation. For simple routine lifts, it typically includes the site supervisor, lifting supervisor, crane

    operator, riggers and signalmen. For more complex lifting operations, it should include other personnel

    such as the lifting engineers who had planned for the lift, banksmen who will serve to coordinate other

    equipment or personnel movement near the zone of operation. The key factors to consider in selecting

    a Lifting Team include:

    Competency only suitably trained and competent personnel should be deployed as part

    of the Lifting Team. During the lifting operation, if any personnel in the team is not

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    21/38

    Page 21of 38

    confident of carrying out the lift e.g., rigger may be unsure on how to rig up the odd-

    shaped item with the limited lifting gears that he has, he must stop the operation and

    request for assistance.

    Composition it is good practice to try to maintain the same group of individuals in a

    Lifting Team so that the trust and rapport among team members can be built up over time.

    Trust becomes very important when the operator does not have a line of sight to the load

    and he has to rely on the instructions that he received from his teammates. There are

    many things that can go wrong in a lifting operation and hence it is important that the

    Lifting Team is familiar with one another. This is especially critical in an emergency

    situation. Care should be taken to ensure that new members to a lifting team are

    appropriately inducted and briefed on the procedures. To facilitate identification, members

    of the Lifting Team should be clearly identifiable by use of reflective jackets or other

    conspicuous clothing or marking.

    Communication the Lifting Team must use a common language that all members can

    understand. Any miscommunications can result in accidents. Hence care should be taken

    when forming a Lifting Team involving individuals from different countries and nationalities.

    Although it is important that the Lifting Team adopts the standard hand/ voice signals to

    facilitate the lifting operation, it is not possible to use hand signals when the operation

    involves lifting the item from ground the floor to the rooftop of a tall building.

    5.3.1 Lifting Supervisor

    The lifting supervisor should be appointed in writing by the contractor. This position is defined as the

    person who is charged with actively supervising the lifting operation on site. The person could be a

    foreman, shift supervisor or other similar capacity.

    In general, all lifting operation must be supervised by the appointed lifting supervisor as he is the main

    person leading and coordinating the operation. A lifting supervisor may be allowed to supervise more

    than one lifting operation at any point in time provided that he is able to discharge his duties

    appropriately e.g., when the two operations are side by side in a close proximity. If so requested by the

    contractor, the Lifting Supervisor should assist to develop the Lifting Plan and seek approval from the

    contractors management.

    Thereafter, the appointed lifting supervisor shall:

    coordinate all lifting activities in accordance with the lifting plan;

    brief all lifting team members on the Lifting Plan, safe lifting procedure and RA;

    ensure that only registered crane operators, appointed riggers and appointed signalmen

    participate in any lifting operation involving the use of mobile and tower cranes;

    ensure that the ground conditions are safe for any lifting operation to be performed;

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    22/38

    Page 22of 38

    be present during all lifting operations; and

    take suitable measures to rectify any unsafe conditions to ensure the lifting operation can

    be conducted safely.

    5.3.2 Lifting Equipment Operator

    There are different types of lifting equipment and the operator is one of the most important personnel

    of the Lifting Team as he is in-charged of the lifting equipment. One of the key competencies of the

    crane operator of mobile, crawler or tower cranes is the ability to read and understand the load

    capacity chart, and to differentiate the Gross Capacity and Net Capacity of the lift. The operator needs

    to know the SWL of the crane relative to the radius in order to prevent overloading of the crane.

    The appointed lifting equipment operator shall:

    carry out the lifting operation in accordance with the Lifting Plan;

    inspect the lifting equipment prior to use to check for abnormalities;

    check that load radius indicator and other safety devices are functioning properly;

    ensure that the ground is stable and the surrounding is free from any structures or

    materials that may obstruct the lifting operation;

    carry out lifting operation only when a lifting supervisor is present on site;

    disengage from any manoeuvre that is dangerous;

    monitor environmental effects such as thunderstorm and strong wind that will affect the

    safe operations of the lift;

    report any defects immediately to the lifting supervisor, and record such defects in

    maintenance log records;

    stop the lift whenever unsafe conditions occur; and check the crane wire rope to ensure it is still within safe use.

    5.3.3 Signalmen

    The appointed signalmen shall be attired in such a way that he/ she will be distinctively identified as

    the signalman.

    The appointed signalmen shall:

    ensure the load is correctly rigged up prior to giving signals to commence the lift;

    give correct and clear signals to the lifting equipment operator to manoeuvre the load

    safely from the point of lift to the destination;

    ensure communications are maintained with the lifting equipment operator throughout the

    lift in accordance with the lifting plan;

    ensure the lift is controlled throughout the duration of the operation;

    ensure that the immediate areas within the lift (start point and final position) are clear of

    any hazards during the manoeuvre;

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    23/38

    Page 23of 38

    maintain his/ her position so as to ensure line of sight during the controlled phase of the lift

    and to ensure this position is free of danger; and

    refrain from handling load/ rigging simultaneously when giving signal to the crane operator.

    5.3.4 Riggers

    The appointed rigger shall be attired in such a way that he/ she will be distinctively identified as the

    rigger.

    The appointed riggers shall:

    ensure all slings, webbings, shackles and other lifting gears used to rig the load are within

    the SWL of the lift, in good condition and duly certified;

    ensure that the load is rigged up in a such a manner that it is stable, balanced (centre of

    gravity beneath the hook) and secured (i.e., no loose items);

    ensure that the lifting equipment operator has been informed of the weight of the load;

    establish tag lines to control the load as it is being manoeuvred; and

    report any defect in the lifting/ rigging and materials to the lifting supervisor.

    5.4 Erection and Maintenance of Lifting Equipment

    The integrity of the lifting equipment to perform its task is highly dependent on how well it is being

    erected and maintained. Therefore, it is important that the contractor appoints qualified and

    experienced mechanics to carry out the erection and maintenance of the lifting equipment, particularly

    if such activities are to be conducted in-house.

    5.4.1 Adherence to manufacturers specification it is critical that the lifting equipment is

    erected, altered or maintained in accordance with the specification by the manufacturer as laid out in

    the operational and maintenance manual. This includes using all genuine components. As with all

    machines to ensure that it can function properly, the lifting equipment is subject to periodic preventive

    maintenance (i.e., daily, monthly or quarterly). It is essential that adequate downtime is built into the

    operation schedule to allow effective maintenance to be carried out and to ensure that maintenance

    personnel are not under pressure to complete the work.

    5.4.2 Competency of mechanics/ erectors such personnel should be provided with training

    relevant to the type of lifting equipment that they are handling (preferably by the manufacturer or their

    agents).

    5.4.3 Record keeping a record of all preventive or corrective maintenance shall be kept. This

    includes records of all testing and certification. Any defects reported should also be recorded into the

    log book.

  • 8/13/2019 Code of Practice for Safe Lifting Operations at Workplaces Online

    24/38

    Page 24of 38

    For erection, alteration of mobile or tower cranes, only Approved Crane Contractors can undertake

    such activities.

    25/38

    Page 25of 38

    SECTION 6: EMERGENCY AND CONTINGENCY PLANNING

    6.1 General

    6.1.1 All lifting operations shall have a documented Emergency Response Procedure (ERP) that

    covers all aspects of the operations. The ERP identifies in a clear and precise manner the

    requirements and actions to be carried out for any foreseeable emergency (with or without any

    casualty). These include:

    toppling of the lifting equipment;

    structural failure of the lifting equipment such as boom fracture;

    dislodgement of the suspended load;

    entanglement of load with nearby structures; and

    recovery of injured personnel in locations where access is limited such as within a tower

    crane.

    6.1.2 The ERP must include the emergency contact details of relevant persons and agencies. Thecontingency procedure should outline all possible emergency situations and identify the recovery

    actions to be taken if they occur.

    6.1.3 The documented procedures shall be tested by conducting ERP drills involving all lifting

    operation personnel. Such ERP drills must be documented and recorded as part of the safe system for

    work. The drills may be conducted as a desk top review which includes all relevant personnel in the

    table top exercise. However, a physical exercise and drill should be carried out whenever possible.

    6.2 Emergency Response Procedures

    6.2.1 The contractor shall develop and document an ERP for the lifting operation. This ERP must be

    communicated to all personnel involved in the lift and made available at prominent locations at the

    workplace. The ERP shall include but not be limited to:

    details of emergency personnel and their contacts including first-aiders;

    emergency communication flowchart;

    roles and responsibilities of the emergency management team;

    emergency services contact details;

    managing injured persons; and

    frequency of exercise and drill to be carried out.

    6.2.2 Lifting operations may be carried out from the ground level or at a high point such as on the

    top of a multi-storey building or in confined areas such as in a tunnel or factory. Each location provides

    specific challenges for the provision of medical and evacuation support. As such, the ERP should as

    much as possible identify access to the location so as to facilitate expeditious medical and evacuation

    support.
